What used Ford Fiesta ST hatchback will I get for my budget?
You’ll need about £14,500 to get inside an ST, and that should buy you a 2018 car with around 30,000 miles on the clock and a full history from a franchised dealer. You'll find plenty of examples in ST-2 form at around that price. To net an ST-3, expect to pay circa £15,500.
That represents a good saving on the cost of a new one (although part of the ST’s great appeal is its value for money new). If you're willing to spend between £16,500 and £19,000, you’ll find plenty of excellent examples from 2019 and 2020 in ST-2 and ST-3 trims. Spend not much more than £20,000 on nearly-new cars.
